【摘要】 依据气调袋装白芦笋的呼吸作用和薄膜的渗气作用在一定条件下达到动态平衡的原理,研究了自发气调保鲜袋(EMAP)的面积、厚度、贮藏质量与袋内O2、CO2的关系。在温度为(3.0±0.5)℃、相对湿度90%～95%贮藏条件下,测定白芦笋贮藏前后的营养和品质指标,确定了白芦笋EMPA贮藏的适宜气体组成为:CO2,5.9%±0.3%;O2,4.2%±0.4%。利用正交试验和多元回归的方法,得出EMAP气体含量与薄膜厚度、薄膜面积、贮藏质量的回归方程,从而设计出用于白芦笋长期贮藏的EMAP。更多还原

【Abstract】 Based on the principle of dynamic balance between the respiration of white asparagus(Asparagus officinalis L.)and permeability of the packaging film under a certain condition,the relationship between the 3 parameters(film area,film thickness and fruit storage weight)and the atmosphere(O2 and CO2)in EMAP was studied.The optimum atmosphere composition in EMAP that stored white asparagus at(3±0.5)℃,RH 90 %-95 % was determined through quality indicators and sensory evaluation at the end of the storage period.The optimum atmosphere composition was CO2:(5.9 %±0.3 %),O2:(4.2 %±0.4 %).Utilizing orthogonal experiment and multiple regression method,the EMAP for storing white asparagus has the advantages of low cost,simple operation,and good effect.更多还原
